💥 Problème
Aujourd'hui, pour éviter plusieurs créations d'épreuves pour un même stade d'examen (race condition), on met un lock sur la ligne de la table
assessmentsconcernés via unSELECT FOR UPDATE.Plusieurs problèmes :
SELECT FOR UPDATEsur la même ligne sont mis en attente. En cas de fort trafic, et si tout dégénère, cela aggrave les problèmes car on agrandit la file d'attente.👩🚀 Proposition
Pour le projet ChatPix a été implémenté un mutex via Redis. On utilise ce mutex.
Côté front, mise en place d'un retry (répétition à définir)
